Context: Multiple environmental factors are associated with development of hypersensitivity pneumonitis (HP), and diagnostic algorithms for the diagnosis of HP have been proposed in recent perspectives. Aims: We analyzed the data of patients with HP from interstitial lung disease (ILD)-India registry. The analysis was performed to (1) find the prevalence of HP, (2) reclassify HP as per a recently proposed classification criterion to assess the level of diagnostic certainty, and (3) identify the causative agents for HP. Setting and Designs: This was a prospective multicenter study of consecutive, consenting adult patients with new-onset ILD from 27 centers across India (March 2012-April 2015). Materials and Methods: The diagnoses were based on prespecified working clinical criteria and multidisciplinary discussions. To assess strength of diagnosis based on available clinical information, patients with HP were subclassified into definite HP, HP with high level of confidence, and HP with low level of confidence using a recent classification scheme. Results: Five hundred and thirteen of 1084 patients with new-onset ILD were clinically diagnosed with HP and subclassified as HP with high level of confidence (380, 74.1%), HP with low level of confidence (106, 20.7%), and definite HP (27, 5.3%). Exposures among patients with HP were birds (odds ratios [OR]: 3.52, P < 0.001), air-conditioners (OR: 2.23, P < 0.001), molds (OR: 1.79, P < 0.001), rural residence (OR: 1.64, P < 0.05), and air-coolers (OR: 1.45, P < 0.05). Conclusions: About 47.3% of patients with new-onset ILD in India were diagnosed with HP, the majority of whom were diagnosed as HP with a high level of confidence. The most common exposures were birds, cooling devices, and visible molds. © 2019 Indian Chest Society.

Background: Interstitial lung disease (ILD) is a complex and heterogeneous group of acute and chronic lung diseases of several known and unknown causes. While clinical practice guidelines (CPG) for idiopathic pulmonary fibrosis (IPF) have been recently updated, CPG for ILD other than IPF are needed. Methods: A working group of multidisciplinary clinicians familiar with clinical management of ILD (pulmonologists, radiologist, pathologist, and rheumatologist) and three epidemiologists selected by the leaderships of Indian Chest Society and National College of Chest Physicians, India, posed questions to address the clinically relevant situation. A systematic search was performed on PubMed, Embase, and Cochrane databases. A modified GRADE approach was used to grade the evidence. The working group discussed the evidence and reached a consensus of opinions for each question following face-to-face discussions. Results: Statements have been made for each specific question and the grade of evidence has been provided after performing a systematic review of literature. For most of the questions addressed, the available evidence was insufficient and of low to very low quality. The consensus of the opinions of the working group has been presented as statements for the questions and not as an evidence-based CPG for the management of ILD. Conclusion: This document provides the guidelines made by consensus of opinions among experts following discussion of systematic review of evidence pertaining to the specific questions for management of ILD other than IPF. It is hoped that this document will help the clinician understand the accumulated evidence and help better management of idiopathic and nonidiopathic interstitial pneumonias. © 2020 Wolters Kluwer Medknow Publications.

Medical Thoracoscopy (MT) is commonly performed by respiratory physicians for diagnostic as well as therapeutic purposes. The aim of the study was to provide evidence-based information regarding all aspects of MT, both as a diagnostic tool and therapeutic aid for pulmonologists across India. The consensus-based guidelines were formulated based on a multistep process using a set of 31 questions. A systematic search of published randomized controlled clinical trials, open labelled studies, case reports and guidelines from electronic databases, like PubMed, EmBase and Cochrane, was performed. The modified grade system was used (1, 2, 3 or usual practice point) to classify the quality of available evidence. Then, a multitude of factors were taken into account, such as volume of evidence, applicability and practicality for implementation to the target population and then strength of recommendation was finalized. MT helps to improve diagnosis and patient management, with reduced risk of post procedure complications. Trainees should perform at least 20 medical thoracoscopy procedures. The diagnostic yield of both rigid and semirigid techniques is comparable. Sterile-graded talc is the ideal agent for chemical pleurodesis. The consensus statement will help pulmonologists to adopt best evidence-based practices during MT for diagnostic and therapeutic purposes. © 2024 Indian Chest Society.
